Be it known that I, HENRY F. DUNN, a citizen of the United States, and a resident of Indianapolis, county of Marion, and State'of Indiana, have invented a certain new and useful Reflector-Renewal Insert; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like numerals refer to like parts.

This invention relates to a headlight or Searchlight, and particularly to the reflector thereof.

s reflectors, and particularly those used on automobiles, vehicles, motor boats and the like, soon become dull and tarnished and even rusted, whereby they lose their properties as reflectors and decrease the efficiency of the light, it is the object of this invention to provide means for cheaply and quickly renewing the reflector, whereby the original reflecting properties of the light ing unit will be returned and a maximum efliiency of light distribution produced. This is accomplished by simply inserting an auxiliary reflector adapted to be placed over the original reflector and secured in position thereon.

The main feature of the invention is to provide a very cheap means of renewing the reflecting properties of the lamp by inserting in the lamp an auxiliary reflector te conform to any size and shape with the original reflector, whereby it is not necessary to construct a comparatively heavy and strong reflector having the necessary flange construction which would be considerably more expensive to manufacture. With this arrangement a very thin reflector having a comparatively small flange could be readily inserted by simply removing the lamp bulb, rim and lens, inserting the auxiliary reflector thereon and replacing them.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims.

In the drawings, Fig. 1 is a central vertical'cross section through the lamp casing, reflector and rim. Fig. 2 is a front elevation of a portion of the lamp showing the position of the reflectors with respect to the mm.

In the drawings there is shown a parabolic lamp casing 10 provided with an axially and inwardly extending lamp socket 11. The casing 10 provided with the usual head 12 and flange 13 about the outer pe riphery thereof. Mounted over the flange portion 13 of the casing, there is a lens closure rim 14 adapted to be secured thereon by means of lugs or pins extending radially inward so as to be passed through the open ing 15 in the rim and turned so as to engage in the slot 16. Embedded in the head 12 there is a wire spring retaining 1nember 17 having inwardly extending curved portions 18 bent forwardly, against which the flanged portion 19 of the reflector 20 is adapted to engage. Between the flange portion 19 and the reflector 20 there'is a head 21 in which is embedded the usual cushion or cord 22 against which the lens 23 is adapted to be forced by the lens clo sure rim 14:. A lamp 2 1 is provided to be mounted. in the lamp socket 11 in position so that the rays emanating therefrom will be reflected in the usual manner. The above described lamp construction illustrated herein is of the usual type, commonly used in connection with Ford automobiles.

The invention herein consists of an auxiliary reflector 25 having a central opening 26, said reflector being of the parabolic type to conform with and lie adjacent to the reflector 20. The auxiliary reflector 25 is provided with a small radially extending flange 27 arranged to embrace the cushioning cord 22 and be pressed thereon by the lens 23 and lens closure rim 14:, as shown in Fig. 1, whereby said auxiliary. reflector will be held rigidly in position within the lamp so as to supersede the reflector 20 in its function and be pressed and maintained in proper position thereby. By means of this arrangement the reflector 25 may be made of relatively light and thin material with a very small flange whereby it may be made much cheaper than the original reflector 20 and will, therefore, give the appearance of, and function as, a new reflector at a considerably less cost.

Upon the original reflector 20decreasing in efficiency because of tarnishing, rust or the like, the lens closure 14 with the lens 23 is removed from the casing, the lamp 24 taken out of the socket 11 and without disturbing the reflector 20 and its positioning, the auxiliary insert reflector 25 is placed flange, alens closure mounted on said casing, a lens in said closure an auxiliary and duplicate reflector for renewing thereflectingproperties of the lamp similarly aperturedand similarly supported and provided with a peripheral flange interposed between the flrst'mentioned peripheral flange and the lens, and means for yieldingly .maintaining said flanges and: lens in abuttable relation to rigidly secure the same Within the casing. a

2. A lamp having a casing, a lamp support Within the casing, a reflector apertured to receive the lamp support and be supported thereby and having a peripheral flange, a lens closure mounted on said casing, a lensin said closure, an auxiliary andduplicate reflector for reneWmg the reflecting properties of the lamp similarly apertured vided with a peripheral flange interposed between the first mentioned peripheral flange and the table relatlon to rigidly secure the same Within the casing, and cushion means between said flanges. j

In Witness whereof, Ihave hereunto affixed my signature. y FL DUNN.
